To all whom it may concern:

Be it known'that l, JOHN S. I'IAM, a citizen of the United States, and resident of "Covington, Allegheny county, Virginia, have machinery for leveling the coke within coke ovens, and particularly to that class of machine for leveling the coke in what are known as beehive ovens, as distinguished from other classes of even. The beehive oven is an oven made in the form of a hemisphere, access being had to the interior thereof, through a central opening at the top and through an opening at the side.

The present invention consists of a device which is carried upon a carriage moving upon a track placed above and preferably at one side of a row of beehive ovens, and which carriage by means of appropriate mechanism, is caused to travel along and over the row of ovens and by further appropriate mechanism, to insert the tool into each oven, so move it horizontally and verticall that all parts of the coke within the oven. will be successfully subjected to its effect, and thereupon to withdraw in and then subject the next oven in the row, to a similar procedure.

The invention will be best understood by reference to the accompanying two sheets of drawings, inwhich Figure 1 is a vertical elevation of the leveling tool in the carriage upon which it moves, shown in connection with an oven in "vertical cross-section.- Fig. 2 is a plan view of the carriage and the tool omitting the oven.

Similar letters refer to similar parts throughout the several views.

In the drawings 0 represents the oven which is provided with an opening 30 in its top and an opening 31 in the sides; S rcpresents a pair of rails extending on top of a row of coke ovens on a suitable platform, "W are the wheels of a truck A.

18 are the axles of the wheels, and T T the supporting hangers.

The truck A carries a circular toothed plate 36 which is supported thereon by rollers, which rollers are made vertically adjustable by means of screws 33 and said plate is arranged to turn on a central bearing on the truck A. The plate 36 carries a torer 26, preferably of the type shown in Fig. 1 which in turn carries a frame 25 attached in any convenient manner. This frame is of the shape shown in Fig. 1, and terminates at each end in appropriate bearings 34 upon which a shaft 9 is carried. The tower is arranged to rotate with the plates 36 on the roilers on the truck A by means of the wheel 38 mounted on the shaft 39 which carries a spur wheel '37 which engages with the teeth on the periphery of the plate 36. The tool. itself consists of' the two leveling armsl, pivoted'togetherat their inner ends to a hollow shaft 2, by means of the pivots 3, as shown in Fig. 1. These arms are raised and lowered by means of the chains 4, which are led into the interior of and up through the hollow shaft 2 by means of the sheaves 32, and are connected to the chain or rope 5. This in turn is 'led over a sheave 6, at the top of the tower 26 as shown in Fig. 1, and down to a inch 7, mounted on the tower and wrovided with a handle 8 whereby the winch maybe turned. When the winch 7 is turned from right to left in Fig. 1, it coils up the rope 5, which draws up the chains 4 and in turn raises the arms 1 to the position shown by the dotted lines in Fig. 1.

The shaft 2 is arranged to slide vertically up and downward in a sleeve 27 attached to or formed on the frame 25 in the manner shown in Fig. 1.. For the purposes of preventing the shaft from dropping out of this sleeve, an adjustable stop collar 24 is provided at the upper end of the shaft which may be adjusted for various heights according to the depth of the charge in the ovens.

The shaft 2 is also provided at its upper end with a gear wheel 8, engaging with a gear wheel 10 at the inner end of the shaft 9. The shaft 9 carries at its outer end a second gear wheel 11, which in turn engages with a gear wheel 12 upon a shaft 13, rotating on the center bearing in bed plate A. At one end of the driving shaft :1. gear wheel 14 is provided, meshing into a gear wheel 15 upon the shaft of motor M. By starting the motor, motion. is imparted through the gearwheels 15 and .14, the shaft 13, the gear wheels 11 and-12, the shaft 9, and the gear wheels 10 and S to the shaft 2, and in this way it may be rotated in either direction at any degree of speed. This motor maybe driven by either steam, compressed air or electricity.' On the bottom 19 the coke'ovens.
